Abstract

Upon transmission of video over low bit rates, it is very common to incur delays, as the frames transmitted cannot be completed in the time allocated using the given bandwidth. The presented thesis proposes a number of methods aimed at facilitating the transmission of video frames over low bit rates, with the emphasis on compressing the video by compromising the less important aspects of the video frame. The presented novel video coding algorithms include a wavelet based coder, a number of variations on a vector based coder, and an alternative rate control algorithm to be applied to the MPEG-4 compression algorithm, which also allows the possibility of error processing on high error channels.
